Also known as "BDN"; Bong Date Night is when a group of friends congregate at a predetermined location (a shelter or place of residence), with members bringing his or her own bong as their "Date". No "Dates" will be shared with any other bro's or ho's, and if any persons show up "dateless", said person or persons shell be shamed and sent home.

1) Hey, let's have a Bong Date Night next Tuesday, I'll bring the "pot"-luck.
2) I was "puffing" on my date last night, dude.
